Processing method of high temperature bending plate of foamed aluminum sheet

Abstract

Provided is a high-temperature plate bending manufacturing method for a foamed aluminum board. A foamed aluminum hook-face board can be manufactured, wherein the bending radius of the foamed aluminum hook-face board is greater than or equal to 0.2 m. The high-temperature plate bending manufacturing method specifically comprises the following steps that (1) the foamed aluminum board is placed in a thermal-insulated heating furnace to be slowly heated, so that the foamed aluminum board is softened at a high temperature, the heating speed is less than or equal to 20 DEG C / minute, and the foamed aluminum board is heated up to 550 DEG C-600 DEG C; (2) the foamed aluminum board after being heated is placed in a plate bending machine, then plate bending manufacturing is conducted on the foamed aluminum board, thermal-insulation improvement is conducted on a roller of the plate bending machine, and adiabatic coating is laid on the surface; (3) after plate bending is conducted, the foamed-aluminum board is conveyed into a spray device, rapid water-cooling is conducted, and the water-cooling speed is higher than 100 DEG C / minute; and (4) the foamed-aluminum board with a specified bending radius is obtained. The manufacturing method for the foamed-aluminum-board high-temperature bending plate is simple, an appropriate heating rate is set, mass industrial production is facilitated, and use of the foamed-aluminum board is promoted.

Description

technical field [0001] The invention relates to the technical field of foamed aluminum, in particular to a high-temperature bending processing method of a foamed aluminum plate. Background technique [0002] The continuous development of modern high-tech has made the problem of electromagnetic interference and electromagnetic compatibility caused by electromagnetic waves increasingly serious, which not only causes interference and damage to electronic instruments and equipment, affects their normal work, and seriously restricts the international competitiveness of my country's electronic products and equipment. It will pollute the environment and endanger human health; in addition, the leakage of electromagnetic waves will also endanger the security of national information security and military core secrets. In particular, the electromagnetic pulse weapon as a new concept weapon has achieved substantial breakthroughs, which can directly strike electronic equipment, power syst...

However, the current research reports on porous absorbing materials are relatively rare, and the analysis of their absorbing mechanism is still in the preliminary stage.

Porous metal foam material is a new type of porous lightweight metal material. People have systematically studied its damping, impact resistance, sound absorption and shock absorption, electromagnetic wave shielding and other properties, but few people have studied its absorbing properties.
